What does a solid white line indicate?

A solid white line is a road marking that indicates the driver must stay in their lane and avoid changing lanes. This marking is often found in areas where lane changes could create hazards, such as near intersections, on the shoulder of the road, or in situations where traffic patterns are particularly dense. The presence of the solid white line serves as a clear guideline for drivers to maintain their current path, promoting safety and reducing the risk of collisions.

In contrast, other markings, such as dashed lines, indicate that lane changes are permissible, and a solid line would not be found in situations where passing is allowed or where a turn is promoted. Understanding these road markings is crucial for safe driving and compliance with traffic regulations.
